Delaware Ivy Asset Strategy Fund
(the “Fund”)

Supplement to the Fund’s Summary Prospectus,
dated July 31, 2023, as amended

Effective February 29, 2024 (the “Effective Date”), the following will replace the first and second paragraphs of the section of the Fund’s summary prospectus entitled “What are the Fund’s principal investment strategies?”:

Delaware Ivy Asset Strategy Fund seeks to achieve its objective by allocating its assets among different asset classes of varying correlation around the globe. Delaware Management Company (Manager), the Fund’s investment manager, primarily invests a portion of the Fund’s assets in global equity securities that the Manager believes can outperform the Fund’s benchmark index, the MSCI ACWI Index, over a full market cycle before taking into account fund expenses (the Equity portion). The Manager then invests the Fund’s remaining assets (the Diversifying portion) in various additional asset classes that may have a lower correlation or volatility than the Equity portion, including but not limited to global fixed-income securities, United States Treasury (Treasury) instruments, precious metals, commodities and cash. The Manager may allocate the Fund’s investments among these different asset classes in different proportions at different times, but generally seeks to invest 50%-80% of the Fund’s total assets (with a long-term target of approximately 65%) in equities or equity-like securities and 20%-50% of the Fund’s total assets (with a long-term target of approximately 35%) in the Diversifying portion. In connection with the active allocation among these different asset classes, Macquarie Investment Management Austria Kapitalanlage AG (MIMAK), the sub-advisor to the Fund, will also manage a tactical/completion sleeve. The tactical/completion sleeve will typically vary from 0% to 20% of the Fund’s total assets and primarily hold derivatives and exchange-traded funds (ETFs). If applicable, the derivatives and ETFs within the tactical/completion sleeve will also be counted towards the asset classes noted above.

For the purposes of this section, a reference to the Manager may also include MIMAK, with respect to its role as sub-advisor of the Fund.

Upon the Effective Date, the following is added to the section of the Fund’s summary prospectus entitled “What are the principal risks of investing in the Fund?”:

Exchange-traded fund risk — The risks of investing in an ETF typically reflect the risks of the instruments in which the ETF invests. Because ETFs are investment companies, a fund will bear its proportionate share of the fees and expenses of an investment in an ETF. As a result, a fund's expenses may be higher and performance may be lower.

Because everyone's tax situation is unique, you should consult your tax professional about federal, state, local, or foreign tax consequences before making an investment in a Fund.
